FRUITS

1. Simple fruit - a fruit formed from a single ovary of a single

flower (monocarpous or syncarpous ovary)

2. Aggregate fruit - a fruit formed from several ovaries of a single

flower (apocarpous) e.g. Anona

3. Multiple fruit- a fruit formed from the ovaries of flowers borne in a compact inflorescence. The fruits unite at maturity e.g. jackfruit, pineapple

Fruits can be divided into three categories:

Simple fruits

1. Dry indehiscent fruits2. Dry dehiscent fruits3. Succulent/Fleshy fruits

A fruit : - pericarp + the seed (inside) - is a ripened ovary/ovaries generally containing one to many seeds inside

Pericarp : exocarp/epicarp + mesocarp + endocarp

** Following pollination and fertilization in a flower, the ovule develops into a seed while the ovary wall forms the fruit pericarp
